The purpose of this study was to estimate the pharmacokinetics of quinidine sulfate in healthy Korean The parameters were examined on 16 volunteers who received a oral single dose(200mg quinidine sulfate). After dosing. blood samples were collected for a period of 24 hours. Plasma samples were analyzed for quinidine sulfate and DL-propranolol hydrochloride(internal standard) by HPLC/UV. The pharmacokinetic parameters (AUC_(0-24hr), AUC_(inf). C_(max), T_(max), K_(a), K_(el), t_(1/2), Vd/F and Cl/F) were calculated from the plasma quinidine sulfate concentration-time data of each volunteer. The computer program "WinNonlin" was used for compartmental analysis. One compartment model with first order input, first order output was chosen as the appropriate pharmacokinetic model. The pharmacokinetic parameters(AUC_(0-24hr). AUC_(inf). C_(max), T_(max), K_(a), K_(el), T_(1/2), Vd/F and Cl/F) calculated 9.47±2.24 ㎍·hr·㎖^(-1), 10.95±2.62 ㎍·hr·㎖^(-1), 0.93±0.16 ㎍/㎖, 1.56±0.45 hr, 1.10±0.36 hr^(-1), 5.17+0.90 hr, 162.38±33.36 L and 22.27±5.35 L/hr, respectively.
